Frequently Asked Questions

Question 1:
Is the vehicle 30% PEG400/0.5% Tween80/5% propylene glycol recommended for in vivo use?

Answer:
S7062 in 30% PEG400/0.5% Tween80/5% propylene glycol at 30 mg/ml is a suspension. For injection, 2% DMSO/30% PEG 300/5% Tween 80/ddH2O at 5 mg/ml is suitable.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
